--------------------------------------------------------------

That was just one example. Check {{getBool()}}, {{getFieldBool()}} methods 
those have the exact same problem, and there are many more.

I am not sure which way we should go (primitive vs Wrapped types) but I am 
inclined towards primitive types.

> {{Long.parseLong()}} returns a primitive type but since method expect to 
> return a {{Long}}, it needs to be wrapped. There are many more method like 
> that. We might be creating a lot of unnecessary objects here.
> I am not sure if JVM catches upto it and somehow optimizes it if these 
> methods are called enough times (or may be compiler does some modifications 
> at compile time)
> Let me know if I am thinking of some premature optimization
